In certain embodiments, the 3rd data-signal Y3+ is similar in appearance to the first data-signal Y1+, and the 4th data-signal Y4-
Similar in appearance to the second data-signal Y2-.Therefore repeated no more in this.
In certain embodiments, in very first time T1, when first switch SW1 turns on according to the first switching signal SW_R, the
One data wire D1 transmits the first data-signal Y1+ the first pixel voltage R+ to the first sub-pixel 111.As second switch SW2
According to the first switching signal SW_R turn on, the second data wire D2 by the second data-signal Y2- the second pixel voltage R- transmit to
Second sub-pixel 112.For equivalent, the first data wire D1 and the second data wire D2 provide the first picture respectively in very first time T1
Plain voltage R+ and the second pixel voltage R- gives the first sub-pixel 111 and the second sub-pixel 112.
Although the first data wire D1 and the second data wire D2 forms near line configuration and the first pixel voltage R+ and the second pixel
Voltage R- polarity is different, but because the first pixel voltage R+ and the second pixel voltage R- correspond to same color, therefore first
Pixel voltage R+ and the second pixel voltage R- is provided in very first time T1.In this case, the first pixel voltage R+
And second the mutual coupling influences of pixel voltage R- reduced, this is beneficial to the display effect of display device 100.

Plain voltage B+ and the 5th pixel voltage B- give the 3rd sub-pixel 113 and the 5th sub-pixel 115.
Although the 3rd data wire D3 and the 4th data wire D4 form near line configuration, due to the 3rd pixel voltage B+ and the
Four pixel voltage G+ have identical polar (such as：Positive polarity), thus the 3rd pixel voltage B+ and the 4th pixel voltage G+ compared with
It will not be affected one another and be coupled to abnormal level.For example, if the 4th pixel voltage has positive polarity but the 3rd picture
Plain voltage has negative polarity, and the 4th pixel voltage may be pulled down to abnormal level by the 3rd pixel voltage.
As shown in figure 3, in certain embodiments, pixel voltage VP represents the 4th pixel voltage G+ waveform.Second
Time T2, when the 4th switch SW4 turns on according to the second switching signal SW_G, the 4th pixel voltage G+ is passed by the 4th switch SW4
Transport to the 4th data wire D4.Now, the 4th pixel voltage G+ rises to first voltage V1.Then, in the 3rd time T3, when the 3rd
Switch SW3 to turn on according to the 3rd switching signal SW_B, the 3rd pixel voltage B+ is transmitted to the 3rd data wire by the 3rd switch SW3
D3.Now, the 4th pixel voltage G+ on the 4th data wire D4 can be by the 3rd pixel voltage B+ couplings on the 3rd data wire D3
The influence of conjunction and rise to voltage V2.Because the 4th pixel voltage G+ with positive polarity is to be coupled to higher voltage level
(being still positive polarity), therefore the operation of display device 100 is not influenceed.
Similar, although the 5th data wire D5 and the 6th data wire D6 forms near line configuration, due to the 5th pixel voltage
B- and the 6th pixel voltage G- have identical polar (such as：Negative polarity), therefore the 5th pixel voltage B- and the 6th pixel
Voltage G- is less likely affected one another and is coupled to abnormal level.For example, if the 6th pixel voltage has negative polarity
But the 5th pixel voltage has positive polarity, the 6th pixel voltage may be pulled to abnormal level by the 5th pixel voltage.
It refer to Fig. 4.Fig. 4 is the part signal according to a kind of display device 400 depicted in some embodiments of the invention
Figure.In certain embodiments, display device 400 includes multiplexer combination 420.In certain embodiments, the multiplexer group in Fig. 4
420 are closed similar in appearance to the multiplexer combination 120 in Fig. 1, therefore is repeated no more in this.Enter below only for Fig. 4 and Fig. 1 Main Differences
Row description, remainder refer to previous embodiment.
Any sub-pixel in Fig. 4 is arranged between two data wires.For example, the first sub-pixel 411 in Fig. 4 is set
Between the first data wire D1 and the 3rd data wire D3.Compared to this, any sub-pixel in Fig. 1 be arranged at another sub-pixel with
Between one data wire.For example, the first sub-pixel 111 in Fig. 1 be arranged at the 4th data wire D4 and the 4th sub-pixel 114 it
Between.
For Fig. 4 examples, the first data wire D1 and the second data wire D2 are arranged at the first sub-pixel 411 and the 5th son
Between pixel 415 and it is arranged between the second sub-pixel 412 and the 3rd sub-pixel 413, the first sub-pixel 411 and the 5th sub-pixel
415 is adjacent and the second sub-pixel 412 is adjacent with the 3rd sub-pixel 413.In this way, the first data wire D1 is formed with the second data wire D2
Near line configures.In addition, the 3rd data wire D3 and the 4th data wire D4 are arranged at the first sub-pixel 411 and the 4th sub-pixel 414
Between, the first sub-pixel 411 is adjacent with the 4th sub-pixel 414.In this way, the 3rd data wire D3 and the 4th data wire D4 are formed closely
Line configures.5th data wire D5 and the 6th data wire D6 are arranged between the 6th sub-pixel 416 and the second sub-pixel 412, the
Six sub-pixels 416 are adjacent with the second sub-pixel 412.In this way, the 5th data wire D5 and the 6th data wire D6 forms near line configuration.
Such as previous embodiment, although the first data wire D1 and the second data wire D2 forms near line configuration and the first pixel electricity
Press R+ it is different from the second pixel voltage R- polarity, but due to the first pixel voltage R+ and the second pixel voltage R- correspond to it is identical
Color and the first pixel voltage R+ and the second pixel voltage R- are provided in very first time T1.In this case, first
Pixel voltage R+ and the second mutual coupling influences of pixel voltage R- are reduced.In addition, though the 3rd data wire D3 and
Four data wire D4 form near line configuration, but because the 3rd pixel voltage B+ and the 4th pixel voltage G+ have identical polar (example
Such as：Positive polarity), therefore the 3rd pixel voltage B+ and the 4th pixel voltage G+ are less likely affected one another and are coupled to exception
Level.Furthermore although the 5th data wire D5 and the 6th data wire D6 form near line configuration, due to the 5th pixel voltage B- and
6th pixel voltage G- have identical polar (such as：Negative polarity), therefore the 5th pixel voltage B- and the 6th pixel voltage G-
Less likely affected one another and be coupled to abnormal level.
In certain embodiments, the distance between wantonly two data wire is less than the pixel wide of any sub-pixel.For example,
The distance between first data wire D1 and the second data wire D2 d2 are less than the pixel wide w2 of the first sub-pixel 411.In some realities
